Summary: Neon Object Storage buckets hold your objects and branch with your database. Create buckets via the Neon Console, the Neon API, or the S3 API. Set the access level to private or public_read to control who can read objects.

Create and manage storage buckets

A bucket is a named container for objects in Neon Object Storage. Buckets are scoped to a branch and inherit from parent branches when a new branch is created. No data is copied on fork.

For object size and storage limits, see Limits.

You can create a bucket from the Neon Console, the Neon CLI, the Neon API, or directly via the S3 API.

Neon Console

In the Neon Console, navigate to your project, select a branch, and open the Object storage tab. Click New bucket, enter a name, choose an access level, and click Create.

neon

neon buckets create my-bucket

Neon API

curl -X POST "https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/buckets" \
  -H "Authorization: Bearer $NEON_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "my-bucket", "access_level": "private"}'

TypeScript

import { S3Client, CreateBucketCommand } from '@aws-sdk/client-s3';

const client = new S3Client({
  region: process.env.AWS_REGION,
  endpoint: process.env.AWS_ENDPOINT_URL_S3,
  credentials: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
  },
  forcePathStyle: true,
});

await client.send(new CreateBucketCommand({ Bucket: 'my-bucket' }));

Python

import boto3, os

client = boto3.client(
    's3',
    region_name=os.environ['AWS_REGION'],
    endpoint_url=os.environ['AWS_ENDPOINT_URL_S3'],
    aws_access_key_id=os.environ['AWS_ACCESS_KEY_ID'],
    aws_secret_access_key=os.environ['AWS_SECRET_ACCESS_KEY'],
)

client.create_bucket(Bucket='my-bucket')

AWS CLI

aws s3api create-bucket \
  --bucket my-bucket \
  --region us-east-2 \
  --endpoint-url "$AWS_ENDPOINT_URL_S3"

To create a public_read bucket with neon:

neon buckets create my-public-bucket --access-level public_read

Note: AWS_ENDPOINT_URL_S3 is your branch's storage endpoint. See Get started for how to obtain it.

Every bucket has an access level that controls who can read objects in it.

The default is private. Set the access level when creating a bucket via the Neon API, or change it from the Object storage tab in the Console.

Note: Access level is set through the Neon Console or API, not through the S3 API. S3 ACL and bucket policy mutation requests (PutBucketAcl, PutBucketPolicy) return 501 Not Implemented. If you need to change access level on an existing bucket, use the Console or Neon API.

public_read example

Objects in a public_read bucket are accessible at:

https://<branch-id>.storage.c-<N>.us-east-2.aws.neon.tech/my-public-bucket/<object-key>

neon

neon buckets list

TypeScript

import { S3Client, ListBucketsCommand } from '@aws-sdk/client-s3';

const { Buckets } = await client.send(new ListBucketsCommand({}));
console.log(Buckets);

Python

response = client.list_buckets()
print(response['Buckets'])

AWS CLI

aws s3api list-buckets --endpoint-url "$AWS_ENDPOINT_URL_S3"

Buckets must be empty before deletion. Delete all objects first, then delete the bucket.

neon

neon buckets delete my-bucket

TypeScript

import { S3Client, DeleteBucketCommand } from '@aws-sdk/client-s3';

await client.send(new DeleteBucketCommand({ Bucket: 'my-bucket' }));

Python

client.delete_bucket(Bucket='my-bucket')

AWS CLI

aws s3api delete-bucket \
  --bucket my-bucket \
  --endpoint-url "$AWS_ENDPOINT_URL_S3"

When you create a new branch, it inherits all buckets from its parent, including the objects already in them at the moment of forking — the same copy-on-write model Neon uses for branching Postgres data, so nothing is duplicated upfront. From that point on:

• Creating or deleting a bucket on a child branch does not affect the parent.
• New uploads, overwrites, and deletes on a child branch are only visible on that branch and its descendants, even for objects that existed at fork time.
• The parent branch continues to see its own state unchanged.

This makes it safe to test bucket changes in a preview branch without affecting production.

• Objects: upload, download, list, and delete objects
• Authentication: credential scopes and branch binding
• Limits: object size and usage limits
